It all started with the Calcutta High Court ordering a CBI probe in August 2021, following allegations of violence by the Opposition BJP after the Bengal assembly poll results were announced on May 2. Following this, several other court-monitored probes by the CBI, including the Bogtui incident, Trinamool deputy panchayat head Bhadu Sheikh's murder case and Congress councillor Tapan Kandu's murder case, among others, were ordered.
